Choosing mailing envelopes often comes down to a simple trade-off: keep the up-front listed price lower, or bring home a larger pack for recurring correspondence. These two white, no-window #10 options share self-seal closure, so the key decision is pack quantity, price, and the extra security language attached to each option.
Quick verdict
Choose 10 Security Self Seal Envelopes 100 Count No Window EnveGuard 4⅛ x 9½\" White when a $15.74 listed price and an everyday-use, small-business, or home-office focus suit your mailing routine. Its title also calls out a security tint and no-window format.
Choose Envelopes Letter Size, 120 Count Business Envelopes #10, Self-Seal Security \| #1 when you would rather start with the larger pack and want the specifically listed security pattern inside and privacy protection. Its $23.23 listed price is $7.49 higher, so it makes the most sense when the additional envelope quantity is the deciding factor.

Where each product wins
Aimoh EnveGuard wins for a lower listed starting price. It is positioned for everyday use, including small businesses and home offices, and its window-less front panel may appeal when you want a consistent blank envelope face for addressed mail. The security-tint wording also makes it a natural fit for routine documents.
The 120-count business-envelope pack wins on quantity and explicitly named privacy protection. It adds 20 envelopes over the EnveGuard pack and pairs its self-seal closure with a security pattern inside. For frequent business correspondence, that larger count is the clearest practical reason to choose it.
Product notes
Aimoh EnveGuard 100-Count #10 Security Envelopes
This Aimoh EnveGuard pack is the straightforward choice for shoppers who want a defined supply of white #10 envelopes without moving to the higher listed price. The no-window format and security-tint description suit addressed letters, invoices, and general office mail where the envelope front needs to stay uncluttered. Self-seal closure removes the need to moisten a flap, while the rectangular 4⅛ x 9½-inch format is clearly stated in the title. Its concrete limitation is quantity: the pack contains 100 envelopes, rather than the 120 in the competing business-envelope pack. Choose it when the lower price and everyday correspondence focus outweigh the need for the larger quantity.
120-Count #10 Business Envelopes
The 120-count business-envelope pack is geared toward shoppers planning a more substantial run of business correspondence. It remains a white, rectangular #10 no-window envelope with self-seal closure, while its description specifically includes a security pattern inside and privacy protection. That combination gives its product language a clear focus on concealing the contents of mailed documents. Its limitation is the listed price of $23.23, which is higher than the EnveGuard option. Choose this pack when having 20 additional envelopes and the explicitly stated privacy-protection feature matter more than keeping the initial listed price as low as possible.
Final choice by use case
For home-office mail, small-business basics, and a lower $15.74 listed price, select Aimoh EnveGuard 100-Count #10 Security Envelopes. For business correspondence that benefits from beginning with 120 envelopes and specifically named privacy protection, select 120-Count #10 Business Envelopes. Since both are white, no-window, self-seal #10 envelopes, the decision is mainly whether the larger pack and its security wording justify the higher listed price for your mailing volume.
